WILLIAM s. EATON, or SAG HARBOR, NEW YOR I PLATE-PRINTING AND EMBossme. MACHINE.

' srncmrcn'rron forming part of r Letters Patent NQ. 752,052, dated February 16, 1904. Application and al so, i903. Serial in. 154,934. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM' SYLVESTER EATON, acitizen of the United States of Americe, and a resident of Sag Harbor, in the county of Suifolk and State of New York, have invented. certain new and useful Improvements in PlatePrinting and Embossing Machines, of which the following is a specification.

This inventionrelates to plate-printing and embossing machines andv it comprises. in brief *neans in conjunction with the oscillatory rocking movement of the die-plate bed, whereby such movement causes the ink-wiping. devices to be actuated in the performance of their functions, the inking-roller to be carried to and from its sourceof supply and .to the dieplate and the inking-roller, to avoid contact with the opposite surface edges of the impression or die plate in the passage to and fro of the latter beneath said roller.

.The invention further includes the combinations of parts and novel arrangements .thereofpermitting the die-plate to .be in;full

;view of the operatoruat all times excepting momentarily when the. actual impressing is taking place, as well as such further combiner tionsand arrangements of parts as will be fully described hereinafter, and particularly pointed out in the claims.

In the drawings accompanying thisappli- 83131011, Figure 1 is aside elevation of my improved machine, -showing the dieplate-bed andmatrix sup' ort=.. extended apart on their joint=pivot, the ie-plate being in process'of passing beneath the inking and wiping rollers. Fig. 2is a similar' view, but showingthe dieplate-bed and matrix-support closed together in theact of creating the impression and embossment and showing the inking-roller atthis time as placed in the actof receiving a fresh quota'of ink from the feed-roller in the reservoir. Figs 3 isa plan view taken on theflinfe X X of Fig. 1, and Fig. 4 is a rearelevation;

will be observed, my improvements are applied in conjunction with a press of the type wherein the bed carrying'the die-plate and a SI PI QI't carrying thelmatrix and sheet t be impressed are pivotally connected by a cams man-shaft and have crank and link connec- 5 tious, whereby the movement of one of said elements is communicated to the other, providing combined advance and retreat actions,

during and incon'sonance witlr which the va-.

i'ious steps of inking, wiping, andprinting, and setting and removing the sheets-beingim pressed are accomplished.

The frame of the machine is indicated ill the drawings by the numeral 1, and the opposite sides 2 2 of the bed 3 are pivotallyoonnect ed with, the, frame by links 4: 4. The inner en teralso serves as the pivotal bearing for the d of bed 3 is pivoted'upon a shaft 5, which latinner .end of a frame 6, that carries the matrixsupport or impression-sheettable.

7 indicates the pulley-shaft; 8, a pinion keyed thereon; 9, a gear-wheel in mesh with said pinion; 10, a transverse shaft upon which said gear 9 is secured; 11, a sleeve looselymounted upon shaft 10 and carrying arms 12 12, Whose opposite 'ends are pivotally connected to the matrix-support frame 6; A disk 13 is keyed upon the shaft 10 and has eccentrically pivoted thereto at l t one end of a crank-arm 15, whose opposite end is pivoted upon a shaft-16 exterior to one of the sides 2 of bed 3. A correspondingcrank-a'rm 17 is similarly pivoted to the gear-wheel 9 and mounted upon the shaft 16 at the opposite side of bed 3 to provide a uniform torque in the operation of the I machine.

The shaft 16 is pivotally connected tothe lower portion of the frame 1, at each side thereof, by-links 18 18. The aforesaid mem-- bers' constitute the-usual parts of this form 10fYfolding1press,whose movement is well known, the weight at the lower end-of the bedsides 2 2 helping to swing back the bed to the open positionlafter each impression. V

Treating first of the improved inking niech:

'anism, 19 indicates a reservoir within which.

afeedrroller- 20 is rotatably mounted, beihg driven by a pulley 21, secured upon its shaft, said pulley21 being couple'dby a pulley-cord 2 2 with a'pulley 23, that is'fast upon a shaft 24, which latter member is provided with pulley with a power-shaft. (Not shown.) The diecentral concentric pad portion 27 and being normally supported atits ends in the adjust- 25, which is in frictional engagement inking roller consists of a rod 26, having a v able bearings 109 at the lower ends of the guide-slots 28 28 in the opposite sidee frame. t will be noted that said slots 28 28, while vertical at their lower portion, inc-line rearwardly at an upward angle at their 0pposite ends, the purpose whereof will presently appear. It will also be noted that the upper surface of the bed 3 is continued rearwardly by the curved arms or ways 29 29, and it is their function with the forward oscillation of the bed 3 to support the rod 26 momentarily in the elevated position to which it has been raised with the rising inclination of the bed and likewise with the return movement.

A pair of bifurcated outwardly-curved fingers 3U,which straddle the rod 26, are pivoted to the frame at either side, as at 31, and each of said pairs of fingers continues into a depending rearwardly-curved arm 32, located in the forward path of the shaft 16, to be moved therewith, whereby when the rod 26 has been elevated beyond the vertical portion of the slots 28 28 the forward fingers of the pairs 30 in their rearward movement will carry the rod 26 up the rearward inclines of. slots 28 28 and will deposit said rod into the depressions 33 33 in the frame, which serve as temporary bearings, while the ink-pad 27 is receiving a fresh quota of ink from the feedroller 20. The'rod 26 is provided with a pinion 34, which is adapted when the pad 27 is upon feed-roller 20 to mesh with a pinion 35 upon the shaft of said feed-roller, thereby rotating said inking-roller oppositely to the rotation of the feed-roller and permitting the latter to supply it uniformly with a film of ink for transference to the die. A spiral spring 36 connects the fingers 30 with the frame and is extended by the rearward movement of said fingers, said spring reacting and drawing the fingers back to their normal position when the shaft 16 moves rearwardly, and thus permits the arms 32 to return to their normal position. With this return action the rearward fingers of the pairs 30, striking against the rod 26, disengage the latter from its temporary bearings and return it tothe slots 28 28, gravity enabling said rod to finally return to its bearings in said slots as the bed 3 assumes the open position. At such time the inkingroller 27 descends upon the die-plate 37, which latter is suitably adjusted and held upon the bed 3. A pinion 38, fast upon the rod 26, at this time bears upon and meshes with a revolving gear 39, that is pivoted at the side of the frame, said gear receiving its rotating motion from a pulley 40, connected thereto and coupled bya pulley-cord 41 with a pulley 42 upon the rotating shaft 24. Thus the inking; roller 27 is caused to rotate upon the die-plate 37 and thoroughly and evenly to ink its surface while passing beneath the said inkingroller. 5

The means for wiping the die-plate to clean its surface from the ink comprise a roller 43, of soft or yielding material, revolubly mounted upon a rod 44, whose opposite ends are passed through vertical slots or ways 45 45 in said slots being pressure to hold the wiping-roller 43 against the surface of the die-plate as the latter passes thereunder.

Paper 50, supplied from a roll 51, whose shaft 52 is journaled in opposite supports 53 53, is passed over a roller 54 and thence around the wiping-roller 43 to provide an intermittently changing wiping surface therefor. From the roller 43 the paper passes over a roller 55, thence over a drum 56, which is fast to its shaft 57, and to a receiving-roll 58, the ends of whose shaft 59 are journaled in bearings 6O 60 in the frame. The drum 56 is provided with a series of longitudinal peripheral surface corrugations 61 to present an enhanced frictional surface-to the paper passed thereover. The shaft 57 of said drum is journaled in bearings in opposite bracket formations 62 62, extending from the frame, and there is also rigidly mounted upon said shaft 57 a yoke composed of-a rod 63,- carrying a pivotal pawl 64, adapted to engage with the corrugations on drum 56, and a pair of arms 65 65, extending right-angularly from the opposite ends of a said rod 63 and rigidly mounted upon the shaft 57. A spring 66, extended between a book 67 on rod 63 and a connection on an arm 62, tensionally holds the .pawl 64 in engagement with the paper upon the drum. Also rigid upon shaft 57 is a spur 68, which extends therefrom right-angularly to the arms 65 65 and has at its free end a friction-roller 69, which bears normally against a cushioned surface upon a horizontal arm 7 0, secured to and extending from a vertically-disposed rod 71. Said rod 71 is passed loosely within the vertical ways or guides 72 73, which latter are secured to the frame, and said rod is provided with a stop 74 to rest upon a cushion 75 at the upper end of the guide 73 to limit its downward movement.

The lower end of rod 71 is furnished with afriction-roller which is located in a position to be struck with an upward blow bya leverarm 105, that is pivoted at 106 in a support 107. The opposite end 76 of said lever is provided with a friction-roller 77 and is located in the path of a cam or beveled projection 7 8, which extends radially from the periphery of disk 13. Thus with the rotation of disk 13 when thecam 78' meets the lever end 76 the latter is depressed-while the lever-arm 105 is elevated and strikes" against the a roller 7 2, thereby sharply raising the rod 71 and causing'the arm 70 tocomrnunicate, through the spur 68, a quick partial turn to the yoke-rod 63, carrying the 'pawlfi i, which latter, being in engagement with the corrugated Surface of drum56 and holding the paper fast thereto,

" shaft 57 whereby at the time when said cam 7 8 performs its function the paper is drawn sharply aroundroller43, and as this action is timed to occurwhen the =r'oller43 is upon the die-plate the surface of the latter is'efi'ectively' cleaned.

The stop Mon rod is provided with a set=screw 83, whereby said stop may be loosened andadjusted at any desired point uponsaid'rod 71 to regulate" its degree of movement-when-struck byth'e lever-arm 105 and the consequent :qualntitybf wiping-paper to be drawn across the surfaceof the die-plate, Fingers 84, extending from the frame, bear against smooth annular ways (not shown) across the corrugated'surface of drum 56, ex

tending to near the-point where the paper leaves said drum in its course of travel, the v purpose of said fingers being to prevent ad- 'hesion of point. i

The shaft 52 of the paper-supply roll is'p'r'ovided with a disk 85, that is fast thereto, and with a pulley 86, loosely mounted thereon, the latter member beingdriven, as by a pulleythe paper to the drum beyond said cord 87, from a power-shaft, Y (Not shown.)

A friction-disk 88,'as'of. leather, is placed upon shaft 52 between said pulley 86 and disk 85,

and a spiral spring 89'is placed about the shaft intermediate and exerting pressure against said pulley 86 and a stop 90., that is fast upon the shaft, whereby with'the'rotation of pulley 86- in an opposite direction to'theintermittent I rotation of shaft 52 a constant tensional friction'is set up to preventenwindingof the pa per from roll 51 excepting as and when a quota thereof "is: drawnawayft hroughf the superior force as applied intermittently with the aforesaid operation of: the feed mechanism;

The sprocket-gear 81'is'loose upon shaft 59 of the "receiving-roll, but has rigidly con nected thereto apair'of disks 91', carrying a pivotal pawl 92, that is in engagement with a ratchet 93 to turnshaftbg a Par ial revolution and wind the paper 50 upon roll 58 with the intermittent movement of sprocket 81. A

spiral spring 94:, intermediate, rollei-58, and a hub 95 provides, with a friction-disk 96, ten-, sional frrcti'o'nal engaging'means between the sprocket 81 and shaft 59 to turn the latter and wind the paper, while the back revolution of sprocket 81 occurs independently-of a corresponding movement of shaft 59, because the pawl 92 is then free from the ratchet 93.

Vertical siots '97 97 are provided in the frame at either side intermediate the slots '28 28 and 45 45, and an idle rod" or roller 98, lo-

cated intermediate the paper-roller 43 and inking roller 27, is engaged at its opposite ends within said slots197 97, being adapted to maintain its relative position intermediate the inking and paper rollers under all conditions of elevation thereof by the movement of bed 3 and the curvedarm's or Ways 29 29, thereby preventing the paperfr'om coming in contact with said inking-roller.

(Located upon the at each sideof and in advance of the, die-plate in either direction are the adjustable'surface projections '99 99,

whose function is when'the bed'3 is moving to the folded or impressing position to meet the i hubs 100 100 upon the inking-roller in advance form its function efliciently in cleaningthe entire surface of the plate.

The usual fingers 101 extend from a-projection 102 at the pivotal end of bed 3 and are tensionally held apart from the table when the latter is extended open, but said fingers serving to hold the sheet'to'be printed upon saidtableas it assumesla vertical position;

Entered in an aperture in the rear of the ink-reservoirQO at a point nearits perimeter is a. nozzle 103, from which excess ink may fipw to a receptacle 10 i, whereby the fluidline in said reservoir is maintained at such level as will avoid liability of the ink as agi .tated fromlfall ing over the sides of the reser- .vo1r. v I

In the operation'of my improved machine with the rotation of thefiy-wheel 108 its shaft 7, having pinion 8, rotates the gear 9, which transmits the same movement to disk 13 and through theflcranks 1 5 and 17and links 18 moves the bed 3 and frame 6 from the open extended position shown in Fig. lto the closed or-foldedfpositio'n shown inFig Q. I In this movement the rollers 26, 98, and M have been raised-in their respective slots by the bed3 and its extensions 2929,. while, thefshaft 16, striking against the arms32 32, has deflected the fingers. 3O 30, carrying the roller 26 With its inking-pad onto the feed inking-roller. Inlftheffirst stage of this movement, however, the die-plate has passed under the inkingroller 27 and thence beneath the Wiping-roller 43., the'cam 7 Set this latter moment having struck the arm .76, causing the lever 105 to Isa strike and force upwardly the rod 71, whose arm 7 has erked upwardly the spur 68, cansing the pawl 64 on'yokero'd 63 to suddenly turn the drum 56 and draw a quota of paper across the surface of roller 43, impinging upon the die. This rapid draft of paper occurring while the die is passing beneath the wiping-roller has the effect'of very efficiently cleaning the ink from the die-surface, and the Y subsequent imprint and embossment is performed without disfigurementof the sheet impressed.
